- *
- *	SkCsGetSendInfo - get checksum information for a send packet
- *
- * Description:
- *	Get all checksum information necessary to send a TCP or UDP packet. The
- *	function checks the IP header passed to it. If the high-level protocol
- *	is either TCP or UDP the pseudo header checksum is calculated and
- *	returned.
- *
- *	The function returns the total length of the IP header (including any
- *	IP option fields), which is the same as the start offset of the IP data
- *	which in turn is the start offset of the TCP or UDP header.
- *
- *	The function also returns the TCP or UDP pseudo header checksum, which
- *	should be used as the start value for the hardware checksum calculation.
- *	(Note that any actual pseudo header checksum can never calculate to
- *	zero.)
- *
- * Note:
- *	There is a bug in the GENESIS ASIC which may lead to wrong checksums.
- *
- * Arguments:
- *	pAc - A pointer to the adapter context struct.
- *
- *	pIpHeader - Pointer to IP header. Must be at least the IP header *not*
- *	including any option fields, i.e. at least 20 bytes.
- *
- *	Note: This pointer will be used to address 8-, 16-, and 32-bit
- *	variables with the respective alignment offsets relative to the pointer.
- *	Thus, the pointer should point to a 32-bit aligned address. If the
- *	target system cannot address 32-bit variables on non 32-bit aligned
- *	addresses, then the pointer *must* point to a 32-bit aligned address.
- *
- *	pPacketInfo - A pointer to the packet information structure for this
- *	packet. Before calling this SkCsGetSendInfo(), the following field must
- *	be initialized:
- *
- *		ProtocolFlags - Initialize with any combination of
- *		SKCS_PROTO_XXX bit flags. SkCsGetSendInfo() will only work on
- *		the protocols specified here. Any protocol(s) not specified
- *		here will be ignored.
- *
- *		Note: Only one checksum can be calculated in hardware. Thus, if
- *		SKCS_PROTO_IP is specified in the 'ProtocolFlags',
- *		SkCsGetSendInfo() must calculate the IP header checksum in
- *		software. It might be a better idea to have the calling
- *		protocol stack calculate the IP header checksum.
- *
- * Returns: N/A
- *	On return, the following fields in 'pPacketInfo' may or may not have
- *	been filled with information, depending on the protocol(s) found in the
- *	packet:
- *
- *	ProtocolFlags - Returns the SKCS_PROTO_XXX bit flags of the protocol(s)
- *	that were both requested by the caller and actually found in the packet.
- *	Protocol(s) not specified by the caller and/or not found in the packet
- *	will have their respective SKCS_PROTO_XXX bit flags reset.
- *
- *	Note: For IP fragments, TCP and UDP packet information is ignored.
- *
- *	IpHeaderLength - The total length in bytes of the complete IP header
- *	including any option fields is returned here. This is the start offset
- *	of the IP data, i.e. the TCP or UDP header if present.
- *
- *	IpHeaderChecksum - If IP has been specified in the 'ProtocolFlags', the
- *	16-bit Internet Checksum of the IP header is returned here. This value
- *	is to be stored into the packet's 'IP Header Checksum' field.
- *
- *	PseudoHeaderChecksum - If this is a TCP or UDP packet and if TCP or UDP
- *	has been specified in the 'ProtocolFlags', the 16-bit Internet Checksum
- *	of the TCP or UDP pseudo header is returned here.

- *	SkCsGetReceiveInfo - verify checksum information for a received packet
- *
- * Description:
- *	Verify a received frame's checksum. The function returns a status code
- *	reflecting the result of the verification.
- *
- * Note:
- *	Before calling this function you have to verify that the frame is
- *	not padded and Checksum1 and Checksum2 are bigger than 1.
- *
- * Arguments:
- *	pAc - Pointer to adapter context struct.
- *
- *	pIpHeader - Pointer to IP header. Must be at least the length in bytes
- *	of the received IP header including any option fields. For UDP packets,
- *	8 additional bytes are needed to access the UDP checksum.
- *
- *	Note: The actual length of the IP header is stored in the lower four
- *	bits of the first octet of the IP header as the number of 4-byte words,
- *	so it must be multiplied by four to get the length in bytes. Thus, the
- *	maximum IP header length is 15 * 4 = 60 bytes.
- *
- *	Checksum1 - The first 16-bit Internet Checksum calculated by the
- *	hardware starting at the offset returned by SkCsSetReceiveFlags().
- *
- *	Checksum2 - The second 16-bit Internet Checksum calculated by the
- *	hardware starting at the offset returned by SkCsSetReceiveFlags().
- *
- * Returns:
- *	SKCS_STATUS_UNKNOWN_IP_VERSION - Not an IP v4 frame.
- *	SKCS_STATUS_IP_CSUM_ERROR - IP checksum error.
- *	SKCS_STATUS_IP_CSUM_ERROR_TCP - IP checksum error in TCP frame.
- *	SKCS_STATUS_IP_CSUM_ERROR_UDP - IP checksum error in UDP frame
- *	SKCS_STATUS_IP_FRAGMENT - IP fragment (IP checksum ok).
- *	SKCS_STATUS_IP_CSUM_OK - IP checksum ok (not a TCP or UDP frame).
- *	SKCS_STATUS_TCP_CSUM_ERROR - TCP checksum error (IP checksum ok).
- *	SKCS_STATUS_UDP_CSUM_ERROR - UDP checksum error (IP checksum ok).
- *	SKCS_STATUS_TCP_CSUM_OK - IP and TCP checksum ok.
- *	SKCS_STATUS_UDP_CSUM_OK - IP and UDP checksum ok.
- *	SKCS_STATUS_IP_CSUM_OK_NO_UDP - IP checksum OK and no UDP checksum.
- *
- *	Note: If SKCS_OVERWRITE_STATUS is defined, the SKCS_STATUS_XXX values
- *	returned here can be defined in some header file by the module using CSUM.
- *	In this way, the calling module can assign return values for its own needs,
